nothing wrong w/knowing how to sew...maybe your friend just gave u a curious look..."like wat is he doing?"...or maybe it's not the sewing..but it's the fact that you're trying to save a pair of jeans..and he probably thinks that u should get a new pair instead of keeping the old pair...instead of assuming..maybe u should ask him......

or r u the 1 that's insecure about your sewing? j/k
